A game of the same name to be played by two or more players in a library, funeral, or any other location where it is generally frowned upon to make noise. The game begins with one person saying "Anus," and then the next person says it again, but slightly louder. The game progresses as such with increasingly loud outbursts, and before long the word is being shouted at full blast. A winner is declared by mutual agreement when it is clear the last Anus can't be bested.

Sal got booted from the library for playing Anus again.
